    • Every element in this universe is composed of matter. But, there are some elements that do not fit right in this criteria. Among the given options, moisture or humidity is the one topping the list. 
    • Moisture refers to the one which was earlier in a liquid state but is now present in the air as tiny droplets. Humidity is no other thing but just moisture in dry air. Therefore, it does not have the significance to be regarded as a matter. 

    Rest all options are a form of matter.
